Standard Specification for Allyl Molding Compounds
STANDARD published on 1.7.2021
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification provides for the identification of three types of allyl molding compounds, based on the general type of filler employed in their manufacture: Type I - High-strength materials, glass-fiber reinforced; Type II - General-purpose mineral filled; and Type III - General-purpose synthetic fiber filler. Types I and II may be subdivided into four classes according to resin composition and use as follows: Class A - Diallyl ortho-phthalate resin, nonflame-retardant; Class B - Diallyl ortho-phthalate resin, flame-retardant; Class C - Diallyl meta-phthalate resin nonflame-retardant; and Class D - Diallyl meta-phthalate resin, flame-retardant. Materials shall be compression molded, conditioned, and tested; and the individual grades shall conform to specified values of impact resistance, flexural strength, permittivity and dissipation factor, insulation resistance, flame resistance, and oxygen index.
